If we elect and put people who are corrupt in power, then the rights of the people will be taken away. Therefore, the people should put a competent and honest person in power, because the people have this power. If they vote, then it is definitely possible to put a competent person in power. But there are some people among the people who put a corrupt person in power for money, due to which that person plays with the rights of the people.
Who forgets the rights of the people to fulfill their own interests, so only a competent and honest person should be voted in to power. The people can do this.
The problem is, how do we even know, and what's to guarantee that the politician we trust won't change their tune once they're in power?
They are only human. They can seem honest and principled and make all the right promises while trying to win people's support. But once they're in power, whether they still stand by those values is another story.
Power , status and money are a huge temptation , and not many people can resist them. That's why most politicians can't be trusted, no matter how decent they were to begin with.
